Emergency power supply in case of emergency. Better to have it and not need it than to need it and not have it...
I am very satisfied with the products. Very high quality of everything.
The inverter is great. Very quiet operation compared to inverters from other companies. It works very well with my new LiFePO4 battery. The remote display does the job perfectly.
Fast delivery and top quality
I have two 100 Ah batteries that I can quickly charge with the charger.
Nopea toimitus yes hyvin pakattua battery 👍🏻
I came across PowerQueen via YouTube.
I found some cheaper batteries online, but I still chose PowerQueen because the reviews convinced me. I tested the 25V 200A battery and I'm also completely satisfied with the PowerQueen solar charge controller. THANK YOU. I will continue to buy from them.
Bel emballage. Site serieux. Livery ok. Prévoyez que les plots sont des vis et non des gros plots ronds comme sur les voitures.Donc the cables are equipped with causses plates with a trou (vis de 10cm) plutôt que du cable dénudé. Bonne installation à tous!
Kaksi reissua tehnyt live kaiulla. Kaikki toimii.
Fast shipping, good price, good quality. I have three 300 Ah LiFePO4 batteries in my camper.
We turn on the refrigerator in March. & out in October..
(Still questions?...
(Of course with solar power)
After underwater damage, I needed new batteries for my fishing boat. Since I was already interested in the new battery technologies, I opted for your LiFe models. The initial charge went perfectly. I can't yet comment on the runtime I calculated. I'll have to wait until spring to start using them on my local lake to get a better idea of their performance.

For me, this is a very interesting thing; so far I'm thrilled.
The battery arrived after 18 days. I'm actively using it in my home system. I'm completely satisfied with your product. Thank you very much!
Fast shipping! Top product. Technical support is better than you could ever expect from a pre-order. I've never had such good contact with anyone as with the PowerQueen team.
This isn't my first purchase and it won't be my last!!! THANK YOU, keep it up!
